Question

What is the heat required to raise the temperature of a body by $1°\mathrm{C}$ called?

Answer 1

Heat required to raise the temperature of a body by $1°\mathrm{C}$:

1. The heat required to raise the temperature of a body by $1°\mathrm{C}$ is termed as the capacity of that body for a thermal change, thus it is called thermal capacity or the heat capacity.
2. It is given by: $C={\displaystyle \frac{\mathrm{\Delta }Q}{\mathrm{\Delta }T}}$
3. Where $\mathrm{Q}$ is denoted as the heat in joules and$\mathrm{T}$is denoted as the temperature in Celsius,
4. The unit of measurement for this is Joule per Kelvin.
5. The delta sign basically denotes the change in heat upon the change in temperature, as heat capacity is known to be an extensive property that depends on the final and the initial states of the body.

Hence, the heat required to raise the temperature of a body by $1°\mathrm{C}$ is called the thermal capacity.
